known that I, HARRY L..HATNA- roan. a citizen of the United States, and

resident ot Gloucester, in the county of Essex and State of h'lassachusetts, have 1nvented new and useful Improvements in Hub-Bearings, of-which the following is a' specification.

My invention is an anti-friction locking system for mounting the hub of a wheelv upon the axle of a carriage and is more particularly designed for heavy service vehicles, such as motor cars and the like.

In the drawings hereto annexed, Figure 1 is a central, longitudinalsection of my improved hub, the rollers and part of the axle being unsectioned; Fig. 2 is a section on line 2-2 of Fig. 1; Fig. 3 is a section on line 3'3 of Fig. l; and Fig. 4: is a section on line 44 of Fig. 1.

In the drawings, A. 's the axle, having at the outer or free end thereof a screwthreaded section a, a cylindrical. section a; a squared section a and a shoulder a B is the hub, carrying flanges 39 between which are bolted the spokes Z) by means of the bolts 6 Shoulders b and 7) are formed within hub B for a purpose hereinafter described. I

Mounted on the square portion a of the axle A is a sleeve D the outer surface of which forms one element of the raceway for one set of rollers E and which butts up against the shoulder (2 At either end this sleeve is screwthreaded for the reception of rings F F. Ring F has an annular groove 1 and ring F has a groove f and a ball race f forthe balls f The rollers E are mounted in the raceway formed between sleeve D and the inner surface of the hub and by the curvature of the inner surface of the hub are forced into perfect parallelism. with the axis of the axle. in the drawings (Fig. 1) the ends of the rollers are diminished in size and each end is provided with a washer 6, one side of.

Upon" 'theother end of the axle is sleeve="D which is subtioii and functionto the ring F and the sleeve carries also a nut G. G and G have annular grooves 51 g for the washers e and nut G has a ball race 9 for balls g".

The nut G is a cap nut having at the innor end of its interior a bolt 9 one end of which engages a spring in recess in the walls of the nut andthe other end of which projects outside the nut to serve as an operating finger piece. As will be seen upon reference to the drawing, the portion of the bolt crossing the end of the axle is cut away except a short section 9 at one side. The

slots 0. and in one of these slots the section g engages after the nut has been screwed to position to lock the nut in position. In order to screw the nut on or off it is, of course, necessary to press the bolt against the force of the spring 9 to throw the section of the bolt out of engaging position. Vl hen the proper adjustment of the nut is attained the bolt is released and the locking section of the bolt engages the first slot opposite to which it comes. A slot 9 in the boltand a pin. g in the nut prevents the bolt from being ejected by the spring 5 The hub is closed at its outer end by electing dustcap H secured upon the end ctthe hub bya bolt h identical in operation with the bolt g".

The operation is as follows: The hearing, made up of sleeve D, rings F F, and their related parts being assembled, is slipped to place upon the axle; the wheel is then put in place and the outer bearing made up of the sleeve 1) and ring G and nut G and related parts is then screwed to position. The adjustment for longitudinal movement of the wheel upon the axle is el'i'ected by means of the nut G, a quarter turn of which, when the threads on the end of the axle are 16 to the inch for example, will give an inward or outward movementof the nut. of

one-siXty-tourth of an inch. The two sets stantially similar in. construction 'and. fu'nc tion to sleeve D. This iesta Y carries". r ng G wluch'is substantially similar inconstruc j w r 'sp aa wb Application filed January 20, 190a. "Seria1No.411;600.

head of the axle is slotted by two or more,

ball bearings cooperate to take end or side thrusts, the amount of play being I governed by the adjustment of the'ball bearmgnut G-'. The weight of the car is carri'ed-by the rollers E mounted in the rings and these rollers owm'g to the functlon of the oppressed ball bearings receive no endfirise stresses. The locking ball bearing nut qand disassembling gives perfect and secure adjustmentand organization with perfect ease in assemblm v the parts as require lwhile the'entire organization combines simplieity,"eas e of adjustment and repair, utility andl'strength in a high degree.
